    Birds live in trees. Squirrels(松鼠) live in trees. But do you know that some frogs（青蛙） live in trees, too?

    The tree frogs are hard to find. They can change color. On green leaves, they stay green. On a branch, they keep brown. Some tree frogs can change from green to gold or blue.

    Tree frogs have legs and wide feet. They have sticky pads (肉趾) at the end of their toes（脚趾）. These sticky toe pads keep the tree frogs from falling off.

    Tree frogs have different colors and markings on their skins(皮肤). Their eyes are different, too. Some have green eyes, some gray. Some frogs' eyes are gold, and some are bright red.

    The sounds they made in spring and summer are different, too. One frog makes a sound like a dog barking(狗叫). Another frog makes a loud noise like a snore（打呼噜）. There is even a frog that whistles（吹口哨）!
